The calculators themselves set no cookies. You can use every calculator on this site with cookies entirely disabled.

Refusing them

Every browser can block or delete cookies, usually under privacy or site settings. Blocking them does not stop the calculators working, because nothing on this site depends on remembering you.

If you are in the European Economic Area or the United Kingdom, a consent banner asks before any non-essential cookie is set, and your choice can be changed at any time from the same banner.

Advertising specifically

To stop advertising being personalized without blocking cookies altogether, use Google Ads Settings or the industry opt-out at optout.aboutads.info.
